RT8015A

3A, 2MHz, Synchronous Step-Down Converter

General Description

Features

^zHigh Efficiency : Up to 95%

The RT8015A is a high efficiency synchronous, step-down

DC/DC converter. Its input voltage range is from 2.6V to

5.5V and provides an adjustable regulated output voltage

from 0.8V to 5V while delivering up to 3A of output current.

^zLow R_DS(ON)Internal Switches : 110mΩ

^zProgrammable Frequency : 300kHz to 2MHz

^zNo Schottky Diode Required

^z0.8V Reference Allows for Low Output Voltage

^zForced Continuous Mode Operation

^zLow Dropout Operation : 100% Duty Cycle

^zRoHS Compliant and 100% Lead (Pb)-Free

The internal synchronous low on-resistance power

switches increase efficiency and eliminate the need for

an external Schottky diode. The switching frequency is

set by an external resistor or can be synchronized to an

external clock. The 100% duty cycle provides low dropout

operation extending battery life in portable systems.

Current mode operation with external compensation

allows the transient response to be optimized over a wide

range of loads and output capacitors.

Applications

z Portable Instruments

z Battery-Powered Equipment

z Notebook Computers

z Distributed Power Systems

z IP Phones

The RT8015A is operated in forced continuous PWM Mode

which minimizes ripple voltage and reduces the noise and

RF interference.

z Digital Cameras

The 100% duty cycle in Low Dropout Operation further

maximize battery life.
